Here is something of intereest from the web page 'All About 2012'...
Dresden codex: On page 74, there is an + and X cross in the sky band as well
as the 8 pointed cross.
The zodiac cross rotates during the precession of the equinoxes against the backdrop of the Galactic Cross with one revolution in 26.000 years (length of a Great Year or Platonic Year). The Galactic Cross rotates with one revolution in 220 million years (time of the revolution of the Solar System around the Galactic Centre). That’s why the Galactic Cross is regarded as a fixated cross during a precession cycle, its rotation can be neglected.
The two crosses (Zodiac Cross and Galactic Cross) form an eight pointed cross and four times during a precession cycle they overlap. The moments of conjunction are called a Great Celestial Conjunction (for details see our paper ‘Crucifying the Earth on the Galactic Cross’ - Smeykavov, Wicherink 2006). It’s the cosmic event that is associated with John Major Jenkins Galactic Alignment. The next one is occurring right now during era-2012 on the winter and summer solstices.
I believe that this may well be the 'sign of the Son of man' that will appear in heavens that Jesus spoke of occuring just before His return, (Matt. 24:30)which I believe may well be within the next 10-13 years.
